Answer:
There is enough evidence to support the attorney’s claim
Step-by-step explanation:
Given that one attorney claims that more than 25% of all the lawyers in Boston advertise for their business.
Sample size n =200
Sample proportion = 
Hypotheses:
(right tailed testat 5% significance level)
Assuming H0 to be true, std error of p = 
Test statistic z = p diff/std error
= 
p value for one tailed =0.0170
Since p <0.05 we reject null hypothesis
There is enough evidence to support the attorney’s claim
Answer:
1. x = -3/2 y+ 1/2z - 2
2. x = -2/3y + -2/3z + 14/3

Answer:</h2>
<em>The course costs, approximately, </em><u><em>$0.16 per hour</em></u><em>.</em>
<h2>
Step-by-step explanation:</h2>
<h3>1. Convert the 10 weeks to hours.</h3>
10 weeks * 7= 70 days
70 days * 24= 1680 hours
<h3>2. Calculate cost/hour.</h3>
<em>Establish a rule of 3.</em>
<em>1680 hours -----> $275</em>
<em>1 hour -----> x</em>
<em>x= (1 hour * $275) / 1680 hours</em>
<em>x= 0.1636904762 ---> Round to the nearest cent.</em>
<em>x= 0.16 ---> Final result.</em>
